Just a quick note that due to a significant influx in the number of spam posts, I have added a captcha to the comments section.  I’ve set it up so that it should generally be readable without too much effort – if you have issues with one of the captcha images, just hit the refresh button a few times and it usually hits on a permutation that’s very readable in a few iterations.  Send me an email if it’s causing you too much grief and I’ll see about tweaking it some more.
